个人简历
张谷，博士，南京大学物理学院副教授。 2012年本科毕业于南京大学物理学院；2018年7月博士毕业于美国杜克大学物理系（凝聚态理论方向）。先后在德国卡尔斯鲁厄理工学院（2018-2021年，博士后）和北京量子信息科学研究院（2021-2025年，助理研究员）从事科研工作。2025年4月起任现职。已发表学术论文20余篇，其中以第一/共同第一作者在PRL发表3篇，Nature Communications发表3篇。
张谷主要从事凝聚态理论研究。近期主要聚焦任意子束缚态的辨认和操控，任意子边界态的编织，以及编织导致的纠缠和奇异输运现象。每年计划招收博士生1-2名。欢迎对凝聚态理论方向有兴趣的同学联系。
研究方向
凝聚态理论，尤其是介观器件中的量子输运理论和拓扑量子现象。主要包括：1. 手性任意子边界态的识别、编织与纠缠；2. 相互作用及耗散效应对拓扑束缚态的影响；3. 强关联和耗散体系中的量子相变与临界行为等。
理论研究手段主要包括有效场论和非平衡格林函数。
